RADIATOR FOR MOTOR VEHICLES.
Specification of Letters Patent. Patented 1 14, 1922 Application filed. April 10, 1920. 7 Serial No. 372,753.
To all whom it may concern:
Be it known that 1, JOHN F. KERR, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Radiators for Motor Vehicles, of which the following is a specification.
This invention relates to an improvement in radiators of that type used in automobile cooling systems, and is more particularly directed to a means for removably securing in place the water tubes connecting the upper and lower water chambers of the radiator.
Heretofore, as generally constructed, such tubes havebeen brazed in place, and in the event of leakage, the removal or replacement of a tube or tubes has required a considerable time and consequent expense. The present invention is directed to a simple construction whereby the tubes may be secured in place in a manner to permit their convenient removal at will in a minimum of time, the tube replacement being equally facilitated by the construction. Hence, the repair of a radiator, requiring the soldering of a tube or tubes, or the replacement of such, is a matter of comparatively small expense. Furthermore, the initial assemblage of the tubes in making up the radiator is also materially cheapened.
The invention in the preferred form of details is illustrated in the accompanying drawings, in which Fig.1 is a view in elevation, partly in section, of a radiator constructed in accordance with the present invention.
Fig. 2 is an enlarged sectional view of a single tube and the means for removably connecting the same in place.
The improved radiator 1, which may be of any conventional or desired outline shape, is formed interiorly to provide an upper waterchamber 2 and a lower water chamber 3. The former is defined by the top of the radiator and an upper header plate 4. while the latter is defined by the bottom of the radiator and a lower header plate ,5. The circulation between the chambers is maintained by a series of tubes 6, held in the respective header plates and opening to the respective chambers.
The present invention is particularly concerned with means whereby these tubes are threaded boss, and closely removably secured in the respective header plates in a manner to permittheir convenient and ready withdrawal when desired, the construction equally facilitating the replacement of the tube.
For the purposes of the invention, the upper and lower header plates 4 and 5 are formed at tube receiving point-s with integral offset bosses, the bosses 'F'of the upper plate extending below the plate, while the bosses 8 of the lower plate extend above such plate. These bosses are shown as integral with the respective plates, being preferably pressed out in any wellknown manner. Both sets of bosses are formed with tube openings 9, ofa size to snuglyreceive the respective tubes 6. The upper end of each tube is formed with an annular end flange 10, which is of a maximum diameter sub stantially equalling the interior diameter of the upper boss 7, so that when positioned this flange will overlie the bottom edge or ledge of the boss 7 around the opening 9.
The lower end of the tube 6 is plain and is adapted to pass snugly through the open ing 9 of the lower boss 8, but preferably does not extend to the plane of the lower plate proper. a bushing 11 for the upper tube connection, and a bushing 12 for the lower connection. As the flange 10 of the tube rests on the ledge of the boss 7 the upper bushing, which is externally threaded at 13 for connection with theinternal threads of the boss 7, will bear upon said flange, and if packing, as a suitable gasket 14 is interposed between the bottom of the boss and the flange 10, a proper seating pressure of the bushing will maintain a non-leaking connection. bushing is threaded at 15 to engage the fits around the projecting end of the tube, a gasket 16 being placed between the upper end of the bushing and the boss, to insure a non-leaking connection at this point. The bushings are to be formed in any suitable way so that they may be engaged by a proper tool for tightening or loosening operations, as is generally indicated at 17.
The upper bushing holds the tube in lace,
The securing means includes- The lower forced upwardly from below, any suitable tool being used for the purpose.
If desired, and as preferred, the top wall of the radiator may be provided with re movable sections 18, removably held in place by watertight connections 19, which sections, on removal afiord amplespace for withdrawing or replacing a particular tube.
Having thus described the invention, what is claimed as new, is 2- 1. An automobile radiator having upper and lower header plates formed with oflset bosses, circulation tubes passing-through said bosses,'flanges on the upper ends of said tubes to cooperate with the upper bosses, whereby the tubes are supported solely through said flanges, and means cooperating with the upper header plate to engage said flanges and securethe tubes in place.
2. An automobile radiator having upper and lower header plates formed with offset bosses, tubes adapted to pass snugly through the bosses and having flanges on their upper ends to cooperate with the upper bosses and limit the downward movement of thetube, the lower end of the tube passing through the boss of the lower header plate and being at all tlmes capable of free vertical movement with respect to said plate, a gasketinterposed between the flange ofthe tubeyand the boss of the upper header plate, and means cooperating with the upper plate and bearing'on the flange of the tube to prevent upward movement of the tube and exert a spreading pressure on the gasket.
8. A radiator having upper and lower header plates formed with receiving bosses,
tubes cooperating with said bosses, each tube being formed to cooperate with the'boss of the upper vheader plate to limit the downward movement olsaid tube, means cooper-v
